Awesome. :3

Overrated engine

May sound crazy but i like gold source better. This is still fantastic but it is missing one thing that will probably come to it one day. NOSTALGIA!

Source is a fantastic engine, capable of great things. It by FAR has he most support available out of all the different engines I have exparamented with. The Hammer editor is fantastically intuitive to use. All around fantastic!

This is the best engine I have ever seen.


Very good, a little outdated but very good.

It's pretty good, but can be buggy as hell.

Probably the best engine of the last decade!

Simply the best game engine in the world

This engine has a lot of pros and cons. One one hand, it's very easy to get into and it can look pretty damn good in the right hands. But on the other hand, you got a 7 year old tool set with mostly command line tools that Valve breaks when ever they get bored. And depending on the version of Source you use(2006, 2007, 2009(no code), AlienSwarm, Portal2(no code)), you might get stuck with half working features(like shadow mapping in 2007).

The main pro is; the fact that it comes with an entire game(2006/2007).

Main con is; half working tools that love to crap out for no apparent reason.

If the tools were in decent shape, and if they would release more fully working(AS has no shader support) codebases. Then I would give it a 10/10 and wouldn't be in the process of learning the UDK.
